Re: Helibars
Go for it; you'll be more comfortable - and that is an important point. No matter what you ride, at some point your personal comfort will reach the point of diminishing returns. It could be anything from "monkey butt" to stiffening joints, but if you ride long enough (actually, anytime you ride long enough)... you'll know.
This bike may be the current love of your life, the full flush of infatuation... but let it/her consistently treat your lower back/wrists/neck/etc... to subtle yet tawdry trauma in the throes of your two-wheeled passion, and you'll eventually be subliminally humming BB King's "The Thrill is Gone" in unguarded moments.
As you age (if you're among the fortunate...), your personal comfort becomes a more significant factor - pay close attention to what your body is trying to convey because it will have a direct impact on your situational awareness and subsequent overall safety. Motorcycling is supposed to be fun; you're likely to have more fun for a longer time if you're more comfortable.
On the other hand, if your "fun" must be measured in terms of discomfort, self-flagellation, overt martyrdom, etc... well, you may have issues beyond the scope of our humble forum.
